USCIS is a mess.

I know someone that still doesn't know whether they have a middle name as far as american authorities are concerned.

Coupled with "two last names" and it gets really messy, really quickly.

Purchases names don't match the CC name.

Bank statements are actually "for another person".

Border crossings are now extra spicy.

And "pray" that your name doesn't resemble a name in some blacklist.
